This invention relstes to e circulsting compressor and has for its principel object o structure comprising e, cylinder or cylinders and their respective pistons end rods connecting the pistons to u cronk to actuate the pistons, all being housed within. s casing comprising e circulsting chemher for sir and hydrsulic substsnce and s crenlo cese, suid circuloting structure to i'unction es n medium between a source of power end n power driven bythe compressor.

it further object of this invention is to construct s compressor hsving s plurality of pumping cylinders placed within e, circulating chamber for substsnce to be compressed es a, power trsnsrnitting its energy through pipes to on engineer engines optionully which is turn will function us onother driving medium for mschinery or other uses for which power is required to sctuete the same.

A further object of this invention is to construct s compressor in such a, wsy that its energy has the capacity to create circulstion of s, pro

- ferred substance therethroueh continuously or to store the same under compression to s prede-= (Ch will-41M) termined degree of force end automatically retein the some uniiormslly.

A still further object of this invention is to position s, series of hell vslves in speced relation around the upper extremity oi the pump cylinder to communicate with a. clrculuting chamber endoutwnrd through other hell valves thet are grouped directly over the upper ends of each cyl inder to discharge force impounded therein through lust seid bell velves into a discharge chumher that exhsusts through c pipe or pipes through which the power is transmitted, and ell oi seid ball valves being inclined to resent by grsvity notion during short periods of idleness due to pulsutive strokes of the pistons.

These end other objects will hereinafter be more fully explained reference being has; to the accompanying drawings forming e, pert oi this specification and in which like cherecters will apply to like parts in the diderent views Referring to the druwincs:

Fig. l is a vertical section through the compressor, the cylinders, sir supply, connecting rods, and crank being in elevation.

'Fig. 2 is a top plan view of the compressor,

it will be seen thnt the some comprises a. circuletine chombcr one crunh case having side walls li, c heed 2, end s bottom 93, said chamber end crsnh case being divided from each other by a. horizontslly disposed web element Positioned in the circulating chamber is s psir of cylinders u, said cylinders at their lower extremities communicating with the crank case wherebypistons t in the cylinders are oiled by a splash system crested by s crank it journslled in its case end the sum crsnh being connected to the pistons by rods t whereby an emcient dual pumping system is arrnnged and being actuated by an engine the drive shsft it of which is secured to the crsnir short by a flanged jointconnection Ill, but not restricted to such connection clone.

Detnchnbly connected to the circulating chum her is u return pipe it as a, conductor for sir or hydraulic substance through the system, and oppositely positioned in the circulating chamber is en sir supply pim it upwardly extending and having at volve it to open and close the pipe wholly or in port as desired to automatically supply on air deficiency in the system chamber, and the said pipe it at its upper extremity hes as conventlonnl sircleener it secured thereto to restrict sediment from entering the chsmber, whereby s desired amount of air is introduced into the chamber should the some he hydraulically charged for pneumstic action to neutralize the shock of pulsotive strokes of the pistons, otherwise it the system wss'cherged solid with water, oil, or the like, the cushion vslve would be void. It will be seen thst e series oi bell valves it surround ouch cylinder in spaced relation and adapted to come municute with the circulsting chamber through their respective spertures A while cavity B of each sold vnlves extend upward and outwerd through the upper side oi said head end such oi? said csvities hove e, slot C to communicote with their respective cylinders whereby substence is dr'awndrom the circulating chamber into the cyl- Figs. 3, 4, 5, and 6 are cross sections taken on inders by s downward stroke oi the pistons end then eiected outward through spertures of bull valve it grouped in another head it, sold groups being in concentric registry with their respective cylinders. end the lost ssid croullo of bull vslves having o plate til lying on the upper side of said head it end through which is positioned groups of apertures 2| that are in registry with last said ball valves in the said head 99 whereby the sold ejected substance is free to enter a. chamber 2% v lying between plate 29 and ahead 23, said head having a flange D to space the head body iroin the said plate to form the clutmber.

The said head 23 hasan outwardly extending nipple 24 at one end thereof and being threaded externally to threadedly pipe 25 as a conductor for tank or engine as power actuating means therefor. It will be seen that heads 2, ll, 23, and plate ll are drilled in registry as at D, and being secured together oil tight by cap screws 20. and the crank case bottom being secured to the side walls 011 tight by cap screws 21.

Positioned on head 23 and upwardly extending is a valve structure comprising a tubular cylinder is, said cylinder being open at one end and having a flange as at E to seat on the head and being secured thereto by cap screws a, said head 23 being apertured as at ill and in axial registry with the opening, the other end of the cylinder having an apertured head ii to close the same. Positioned in the cylinder is a valve structure comprising a stem 32 having a piston 33 thereon to cover the aperture 3!, and a coil spring 34 is wound on the stem so that one end thereof seats on the piston while the other end seats on the apertured head to clamp the piston to close engagement over the aperture, the stem extending outward through the aperture of the head and having one end of a bell crank it rockably connected thereto by a link ll while the elbow of the crank is rockably connected to the upper end of an arm 31, the lower end or which is integrally joined to the cylinder. Rockably connected to theother end of the bell crank is an arm 38 that extends to and rockably connects to' a butter-fly lever as of 'a conventionai'internal combustion engine carburetor whereby the speed of the engine is automatically controlledby the compressor as the said tubular valve. s tructure communicates with chamber 22 that contains substance that is normally compressed which inlturn acts upon the said tubular control valve that functions as a safety device for the compressor. Positioned in the cylinder adjacent its apertured head is anaperture 40 to function asa breather for the valve piston.

Such modifications may be made as lie within the scope of the appended claims.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

engage an outward flow substance to a storage 1. In a circulating compressor of the class described comprising a crankcase and a crank in the case, and an engine to turn the crank, a cylinder having a piston and rod connecting with the crank, the cylinder having a plurality of ducts in spaced relation around the cylinder'at its upper extremity, a circulating chamber surrounding the cylinder from a spaced distance downward to a head surrounding the head externally and an intake for the circulating chamber, gravity actuated ball valves to communicate with the cylinder through its ducts, while the balls are ositioned in a lower plain seating in openings that communicate with the circulating chamber, a head to close the upper extremity of the cylinder and its respective ball valves and duct openings, the head being of suitable thickness, and a cluster of gravity actuated ball valves concentrically positioned to communicate with the cylinder for air exclusion outward through the head, a plate to lie on the head at its upper extremity and being securedthereto, said plate having a series of clustered ports, each cluster being in registry with the last said gravity actuated ball valves, a flanged head, the flange seating on the plate as spacing means for the head from the plate whereby an exhaust chamber is formed to receive air forced therein through the clustered apertures, and an exhaust pipe for the chamber.

2. In a circulating compressor as recited in 7 claim 1, a safety device for a predetermined pressure, said device being seated on the flanged head and-comprising a tubular cylinder having a head to close one end, the other end being open to communicate with the exhaust chamber through an opening in the head of the said chamber, a spring tensioned piston to resist a predetermined force within the compressor, the piston having a rod extending axial through the tubular cylinder and outward from its head, a series of levers rockably connected and to said rod as controlling means for the engine fuel whereby the force of the en- I gine is automatically controlled to maintain .a

uniformity of pressure in the compressor.
